Struct packet::ParseMetadata

pub struct ParseMetadata { /* private fields */ }

Metadata about a previously-parsed packet used to undo its parsing.

See GrowBuffer::undo_parse for more details.

Implementations

impl ParseMetadata

pub fn from_packet( header_len: usize, body_len: usize, footer_len: usize ) -> ParseMetadata

Constructs a new ParseMetadata from information about a packet.

pub fn from_inner_packet(len: usize) -> ParseMetadata

Constructs a new ParseMetadata from information about an inner packet.

Since inner packets do not have a header/body/footer distinction (at least from the perspective of the utilities in this crate), we arbitrarily produce a ParseMetadata with a header length and no body or footer lengths. Thus, from_inner_packet(len) is equivalent to from_packet(len, 0, 0).

pub fn header_len(&self) -> usize

Gets the header length.

header_len returns the length of the header of the packet described by this ParseMetadata.

pub fn body_len(&self) -> usize

Gets the body length.

body_len returns the length of the body of the packet described by this ParseMetadata.

pub fn footer_len(&self) -> usize

Gets the footer length.

footer_len returns the length of the footer of the packet described by this ParseMetadata.
